That is half the picture. The more north you are the later in the evening sunlight lasts. I grew up near Minneapolis - in winter there is nothing you can do to get daylight both before and after school hours, and when close to the equinox it is hard to even hit one if you sun during recess as well (one hour after school starts or one hour before it ends).

Daylight savings time is useless in the north because there isn't enough daylight in winter to do anything useful with no matter what you do. In summer it is pointless as there is far more daylight than you need and so you have to learn to sleep with the sun up.
